To all whom it -mag/ concern:

Be it known that l. lvrincat J1 Mannen, a

citizen of the UnitedStates, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and uset'ul Improvements in VVateL-Closets.- of which thc following is a specification.

The invention relates to water closets for general use, but closets embodying the in`- veution are particularly well adapted for use, in the cells or rooms of prisons and similar institutions.

Generally stated the object of the invention is to provide a water closet of improved constrln-tion, but, as above intimated. a specitic object ot' the invention is to provide a water closet which. for reasons hereinafter stated or intimated, is particularly adapted for the specific purpose named.

The invention consists in the features of novelty' that are hereinafter described with reference to the accompanying drawings` which are made a part of this specification, and in which:

Figure l is a plan view of a water closet embodying the invention, all parts back of the bowl being omitted. Fig. Q is a view, partly in vertical section and partly in elevation of a water closet embodying the invention, the lower portion o the Lowl being omitted. Fig. 3 is an enlarged vertical section of a fragment of the bowl, a port-ion of the valve device, and the manually controlled devices by which the valves are moved in one direction to fill the tank and permitted to be moved in the opposite direction to empty the tank and flush the bowl. Fig. 4 is a horizontal section, on the scale of Fig. 1, showing, in detail; thc hinge-joint of the cover (or seat). Fig. 5 is an elevation of a `noditication.

represents the bovil only the upper por: tion of which is sliown,"tl1e invention being in no wise concerned with the lower portion, or trap. The bowl may be of metal or earthcnware-preferably the latter.

. The seat for the occupant, when the closet is used as such` is preferably formed directly on the bowl itself as shown at a (in fact, is

provided by the contour of the top wall of the so-called hollow-rim althoughv this is not essential and if desired the customary hinged seat may be used. lVith the back of this hollotiY rim rcommunicates a passage n' the rear end ot which proceeds upward withina vertical extension A located at the hack of the bowl and extending upward above the top o t' the bowl or the` seat thereon. The extension has a horizontal passage or opening n. extending completely through it, from front. to back, and communicating with the passage a. The back of thc bowl is vertical and rests against a wall or perth tion B, to which it is secured by any suitable means, but preferably (in part, at least) Dy bolts C passing through the extension A". Through the opening a. passes a tube D which constitutes the main ortion of the shell or casing of a valve J, hereinafter called the outlet valve. The forward wall of the shell or casing is thickened and has a flange rl which bears against the front side of the extension through the medium of a packing ring d and onto its projecting rear end Il, which is threaded bath internally and externally is turned a nut F between which and the back of the extension A' are interposed a washer j' and packing ring f', which lat-ter occupies a depression in thc face of the former. By turning up the nut; F the extension A may be clamped between the nut and tlange with sufficient force to hold the shell or casing securely in place, with its outlet opening c opposite the -passage fr.

The. valve E is carried b v a stem (l and is held normally unseated by a spring, g. The rear end of this stein is in engagement. or substantial engagement, with the forward end of the stein .7i of a "alve H, (hereinafter called the inlet. valve) which is held normally seated by a spring L. The inlet valve controls communication between thc service. or supply pipe I and a pipe J extending to the tank K. the pipe J boing also in communication '.vith the casing of the'outlet valve F. This valve-device, so far as above described (exce )ting for the thicl'cencd end wall of the shell).-is constructed and operates substantially as does thc valve device shown in Letters PatentNumber $39,552, which were granted to me October 13, 1896, and which has reciprocally operating inlct.

and outlet. valves. Suflice it to say that the forward end of the stem (i projects through and beyond the frontwall of thc shell ov casing in position to be engaged by a malinally controlled device adapted to force it. inward in opposition to the springs y and Il and thereby scat the valve E and unseatv the valve ll. This closes communication liotwcen the tank and bowl and opens conl- Q esi munication between the service pifpe and the tank, permitting the latter to 'lL Upon the removal of the pressure from the rorward end of the stem G, the springs will unseat the valve E and seat the valve H. This closes communication between the service pipe and tank and opens Acommiinication between the tank and bowh'permitting the contents of the tank to be. dsrharged into the bowl. The front wall of the casing is of considerablethickness and that portion of the stem G which occu ies the opening tlirou h it when the val-ve lis iinseated, is provi cd with one or more annular grooves q g which receive wat/er andthe water in these grooves serves as a water packing The front end of the valve casing carries a pair of forwardly extending lugs or arms Lrthe forward ends of which have perforations occupied b v the intle M of a hinge. This pintle is referab y made in two parts of equal lengt and near their outer ends said parts pass through perforations in the I upper ends of posts or standards N rising from and secured to the bowl, to which posts the pintlc is secured by binding screws n. The pintle passes also through perforatlons in foiirlugs or ears, that are carried byand project frearward, from a metallic plate or iittingO to which the cover P or4 its equi va' lent is secured, two of said lugs (Q) being adjacent to the posts N (preferably outside of them) and the other two (Q.) being adjacent to the arms or lugs L (preferablyv between them). With the lugs or ears .l and Q thus located the cover is prevented from moving side-wise (in the direction of l' the axis of the pintle) and all tendency to move the pintlo endwise, b v sidewise strains put n on the cover, is' thereby avoided. The lugs (5 are provided, also, with perforations located below the pintle openings, for r e ceiving the ivotal support 1* of an eccentric y cam R whic is located between the lugs Q and directly op osite the projecting end of the valve stem (E), which it is adapted to en gage. The cam is carried by the part P and is so located that it turns about the axis of movement of said art. It is directly interposed between sai art and the'v valve stem and is so shaped t at when Asaid part. is lifted, the valve stem will be moved inward with the results already described. lt is attached to said part only through the medium of its pivot -r and is provided with a shoulder r which may, under perfect conditions, directly engage said part, whereby it' is compelled to move with said' part, turning about an axis co-incident with the axis of the pintles M. The cam is provided also with a shoulderxi'" adapted to be engaged b v a set. screw S, having threaded engagement with. a lng o carried by the fitting. so that when the screw is in engagement with-the. shoulder be transmitted to the cam through the inediiini of said screw. The use of a screw interposed between tlu-l cover and the cani has the advantage of makin the cam adjustable, either initially or or taking up wear. tion or the other the throw of the cam may be regulated. By driving the screw inward the radius intervening between' the axis of thel pintle. M (which is also the axis about whir i the cam ismoved by the cover or part P), and the point on the cam with which tho valve-stem contacts is increased, and vice versa From the foregoing it will be .seen that when the cover is lifted the seat on the hollow rim of the bowl will be uncovered, thus conditioning the closet for use as a water closet or as a urinal, and meanwhile the tank will be filled, and when the cover is lowered the seat on the hollow rini of the bowl will be covered and the bowl will be hushed. 'lVhen in its lowered position the cover is available for use as a scat--as a substitute for a chair, bench, or the like, and this and other things incident to the described construction makes the closet particularly ada ted for use in the cells of prisons and similar institutions.

It will be observed that the bowl is relieved of all strain incident to the raising and the lowering of the part P, and in this connection the 4 part P may, be regarded either as a cover, such as is shown in the drawings, or as a hinged seat of customary construction. The relieving of the bowl ofl strains is due to the fact that the op osing' strains resulting from the raisingand lowering of the part I are transmitted in one direction from the part P to the valve casing. through cam R, valve stem G, valve E and its seat, and react from the casing to the part P through the medium of the lugs L, pintie M and lugs Q'. A Y

The seat for the valve E is formed on the forward end of a tube e which occupies the shell or casing of the valve E, and Vmay-be adjusted therein by turning it, the valveseat tube and shell-being provided with external and internal threads, respectively. The valve-seat tube has within it a spider e, having 'a non circular opemn through which a non circular portion o the valve stem passes, so est be capable of endwise but incapable of rot ry movement, relatively to the valve-seat tube. This spider also forms a bearing for the rear end of the spring g, and this bearing .being thus carried by the shell or casing of the outlet. valve, instead of by a second part or fitting in rear thereof the assembling and adjustingof the parts accessory to the outlet valve 1s facilitated. As shown in the drawings the casing D of the outlet valve is attached to Athe fit-l o r", tln` upward movement ofthe cover will ting D', which forms a part of the waterlli' adjusting the screw in one direc-` 'wav and with whit-h the easing of the inlet valve ll is integral. b v a eap 'l` screwed on to the rear end ot` the easing l) and having an internal shoulder engaging th.` shoulder l 3 ou a short tube Il serewed into the fitting l'so that ,bv the sin fle aet ot' inrninf the g eap in ont` direetion oi' the other. the easing l) and fitting may be eoupled or uneoupled without disturbing any ot' their eontained parts. This eoupliug means. while preferable. may nevertheless he .substituted by any other means without departing from the spirit ofthe invention. this part ot' whieh is eoneerned more partieularly with the selfeontained eliaraeter of the outlet valve rl@- viee. lt will be seen that the shell or 'asing of this valve deviee eontaius and earries' all ofthe parts aeeessory tothe valve so that the valve deviee a's a whole is an entity which ina v be free-I v handled without the displacement of any of its parts or the alteringr of an v o'." its adjustments. B v adjiistably mounting.r the seat for thi.- valve E directly upon the Shell or easing. the parts may he assembled and initially adjusted before the titting is eoipled to the easing and after they are coupled they may be` separated without disturbing the szaid adjustment. and i this would ,not be posaible if the Seat for the 3o valves E were earried b v the fitting D;

.\s Shown in Figs. 1 to 4 of the drawings alid as above deserihed. the part l is a rover for the bowl luit.it is also. in t'aet and in meehauieal et'l'eet. so fav as the operation of the valve is voneerned. a lever whieli operates upon the valve-stein through theniedinm of the (':iiii ll.
